Bio

Roger Thompson's computing career began as a mainframe engineer in Australia in 1972. In 1979, he started a business in Australia to develop software for the then-emerging microcomputer industry. He now recalls, with some amusement, that he called it Microsoft and remembers being upset to discover that "some American company had stolen his name." In 1987, he co-founded the first Australian anti-virus company, Leprechaun Software, and launched Virus Buster. After moving to the United States, Roger started Thompson Network Software, which developed The Doctor range of products; the company was sold to On Technology. He was most recently Director of Malicious Content Research at Computer Associates. In November 2003, Roger testified before Congress in support of legislation to protect computer users against spyware.
